C17200 Beryllium Bronze Performance:
- Beryllium bronze is a precipitation hardening alloy. After solution
aging treatment, it has high strength, hardness, fatigue limit and
elastic limit, small elastic hysteresis, and has corrosion
resistance and processing properties.
- Wear resistance, low temperature resistance, non-magnetic, high
conductivity, impact and no sparks.
- Strong electrical conductivity. It also has good fluidity and the
ability to reproduce fine patterns.
- Beryllium copper alloy is an indispensable submarine cable repeater
structure. Alternative materials.

Q1:Could you produce Beryllium Copper strip by Mill Hardened
process.
A1:Yes, we could produce AM(TM00), 1/2HM(TM01).HM(TM04) XHM(TM06)
XHMS(TM08).,we are the only factory could do harden strip in China.
Q2: What’s the advantages the Beryllium Copper of CUBERYLLIUM®.
A2: 1: The Biggest Coil weight could be reach 1200kg/Coil
2:We are the only one who melting by Vacuum semi-Continuous
Furnace.
3:Surface further polishing for top clients.
Q3: Why you melting by Vacuum semi-Continuous Furnace.
A3:Could be get the Cast ingot without gas,smaller segregation,
Grain Refinement
Q4: What's the payment terms?
A4: We accept T/T, L/C, Paypal etc. It can be negotiated when the
amount is different.
